Solarpunk I suspect is more important that we know, because I think rich subcultures are the seeds of massive growth.
It's just some funny drawings and internet fanfic twigging our sense of novelty on HN now, but when you see it as representing the desires and longings of young people for wilderness, and also know people who left cities in the last 10y, they were the thin edge of the wedge, where post-pandemic, younger people are leaving cities to get on the real estate ladder, with remote work and amazon-style supply chains, and they are family-inclined. It incorporates passive and renewable energy techs, argritech, biotech, cannabis-driven value added production, organic and small scale food production, brewing and distilling, civic minded prepping, local vs. global, etc.
I'm interested in when solarpunk blips on the radar because to me it is an aesthetic that represents new growth.
